SPINDLE.

SPECIFICATION forming part of Letters Patent No. 263,300, dated August29, 1882.

Application filed May 1, 1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. ALLEN, of Ayer, county of Middlesex, Stateof Massachusetts, have invented an Improvement in Spindles, of which thefollowing description, in connection with theaccompanying drawings, is aspecification.

My invention relates to spindles of that class known asdead-spindles,and has forits object a novel support for theshell-spindle which carries the bobbin, whereby the shell-spindle maymove laterally or radially upon the standard within it to enable theshell-spindle, with its bobbin, to center itself to its load.

In this my invention I have placed an independent step between the upperend of the standard and the interior of the shell-spindle, and have somounted the step, as herein shown, by a slot-andpin and stem-and-socketconnection that the shell-spindle and step are free to move to a certainextent in every direction.

This invention is an improvementon United States Patent No. 244,712,wherein the lower end of the standard below the whirl is fitted looselyinto a socketed base. In the construction shown in the said patent thepull of the band on the whirl tends to deflect the entire standard, andhence the spindle, from the perpendicular, which is extremelyobjectionable. To overcome the objections to such construction I havesecured thestandard rigidly in the base, so that it cannot movelaterally at any point below the whirl, and hence the pull of the bandis resisted by arigid standard; but to enable the shell, withits load,to center itself correctly I have provided the standard at a point abovethe band-pull with a freely-moving step, the rotation of which isprevented by a pin, as will be described.

Figure 1 represents in partial vertical section a dead-spindle embodyingmy invention; Fig. 2, a detail of the same, showing a different view ofthe step; Fig. 3, a section of Fig. l on the dotted line 00 w, and Fig.4 a broken detail of a modification.

The standard a, about which is placed the bobbin carrying shell-spindleb, upon which is secured the whirl c, is rigidly fixed to asocket in thebase 2 of the oil-well F. At its upper end (see Figs. 1 and 2) thestandard a is provided with a longitudinal socket, into which is droppedloosely the smaller pintle or stem 3 of the step d. The stem 3 is boredtransversely to form a hole for the reception of the small pin 6, whichis extended through the said hole loosely, and serves as a connectionbetween the step and the standard a to prevent the rotation of the stepwith the shell-spindle b,- but owing to the fact that the pin cholds thestep loosely, and that the Stem-and-socket connection between the rodand shell-spindle also ai fords space between them, the step is leftcomparatively free to move with the shell-spindle as the latter seeksits true center of rotation. The upper portion of the step d fits theshellspindle b closely; but the shell-spindle does not touch thestandard a, except at its lower portion, near or within the whirl.

I have shown amodification in Fig. 4 wherein the upper end of thestandard a is provided with a reduced stem to fit a hole or socket ofconsiderably larger diameterin the Step, such construction being theconverse of that shown in Figs. 1 and 2, and an obvious equivalent, thepin ein the said figurealso enteringloosely a hole of somewhat largerdiameter in the reduced stem of the upper end of the standard, butfitting the hole in the step closely.

The oil-well, its cover g, and annular depending collar h are all castin one piece.

The standard has a suitable groove, n, for oil.

The step-rail is marked m.

The shell-spindle is prevented from rising too far by screw 01. andcollar 1).

I claim- The standard a and the base, into which itis fitted rigidly,and the loose step supported, substantially as described, at the top ofthe said standard, combined with a shell-spindle, substantially as setforth.

In testimony whereofIhave signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE H. ALLEN.
